我正在运行Centos 7，需要安装check_mk代理来获取机器统计信息。我已经Centos 7通过一个包在同一集群的许多其他人中成功安装了代理，rpm但是在当前机器上我得到了这个输出：
Running transaction
Warning: RPMDB altered outside of yum.
Installing : check-mk-agent-1.5.0p9-1.noarch 1/1
Activating startscript of xinetd
Note: Forwarding request to 'systemctl enable xinetd.service'.
Failed to execute operation: Argument list too long
Starting xinetd...
Redirecting to /bin/systemctl start xinetd.service
Failed to start xinetd.service: Argument list too long
See system logs and 'systemctl status xinetd.service' for details.
Verifying : check-mk-agent-1.5.0p9-1.noarch 1/1
Installed:
check-mk-agent.noarch 0:1.5.0p9-1
还注意到系统无法使用任何systemd新服务。我为测试目的制作了一个垃圾服务，它的配置文件/etc/systemd/system被命名test.service并简单地调用了/root/test_service/. 这是服务文件：
[Unit]
Description=Example systemd service.
[Service]
Type=simple
ExecStart=/root/test_service/service
[Install]
WantedBy=multi-user.target
这是python脚本：
#!/usr/bin/python
import time
i = 0
while True:
print(i)
time.sleep(2)
i += 1
运行systemctl start test.service我得到错误：
Failed to start test.service: Argument list too long
See system logs and 'systemctl status test.service' for details.
此外，systemd似乎工作正常，因为我有很多其他服务启动并运行。还尝试启动xinetd服务导致相同的错误。
任何线索将不胜感激。
